# Exploiting API Injection Vulnerabilities

> Use when tests APIs for injection vulnerabilities including SQL injection, NoSQL injection, OS command injection, LDAP injection, and Server-Side Request Forgery (SSRF) through API parameters, headers, and request bodies. The tester crafts malicious payloads targeting different backend technologies and injection contexts to extract data, execute commands, or access internal services. Maps to OWASP API8:2023 Security Misconfiguration and API7:2023 SSRF.

# Exploiting Api Injection Vulnerabilities

## Overview

Cybersecurity skill for exploiting api injection vulnerabilities. Follows industry best practices and security standards.

## When to Use

**Trigger phrases:**
- "exploiting api injection vulnerabilities"
- "Use when working with exploiting api injection vulnerabilities"


- Testing API endpoints that accept user input for database queries, system commands, or external requests
- Assessing APIs that interact with SQL databases, NoSQL stores (MongoDB, Redis), LDAP directories, or external URLs
- Evaluating input validation and parameterized query usage across all API endpoints
- Testing for SSRF where API parameters accept URLs or hostnames that trigger server-side requests
- Identifying injection points in headers, path parameters, query strings, and JSON/XML request bodies

**Do not use** without written authorization. Injection testing can modify or destroy data and compromise backend systems.


## When NOT to Use

- When you lack proper authorization for testing
- For production systems without change management
- When the task requires legal or compliance expertise beyond technical scope


## Prerequisites

- Written authorization specifying target API and backend systems in scope
- Python 3.10+ with `requests` library
- SQLMap for automated SQL injection detection and exploitation
- Burp Suite Professional with Active Scan capabilities
- Knowledge of the backend database technology (MySQL, PostgreSQL, MongoDB, Redis)
- Isolated test environment to avoid production data corruption


> **Legal Notice:** This skill is for authorized security testing and educational purposes only. Unauthorized use against systems you do not own or have written permission to test is illegal and may violate computer fraud laws.

## Workflow

```python
# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}
```

1. **Reconnaissance** — Gather information about the target related to api injection vulnerabilities. Identify attack surface.
2. **Vulnerability Identification** — Enumerate potential api injection vulnerabilities weaknesses using automated and manual techniques.
3. **Exploit Development/Selection** — Choose or develop exploits targeting identified api injection vulnerabilities vulnerabilities.
4. **Execution** — Execute the api injection vulnerabilities test in a controlled manner with proper authorization.
5. **Post-Exploitation** — Document the impact and extent of successful exploitation.
6. **Reporting** — Write detailed findings with reproduction steps, impact assessment, and remediation guidance.

## Tools

- **Vulnerability Scanner** — Automated weakness identification
- **Exploitation Framework** — Controlled exploitation testing
- **Reporting Tool** — Findings documentation and tracking


## Process

1. **Reconnaissance** — Gather target information, identify attack surface, enumerate services
1. **Analysis/Exploitation** — Execute the technique, analyze results, document findings
1. **Reporting** — Document IOCs, write findings, provide remediation recommendations

## Verification

- [ ] All api injection vulnerabilities procedures executed completely and documented
- [ ] Findings validated against multiple data sources
- [ ] False positives identified and filtered
- [ ] Results documented with evidence and timestamps
- [ ] Recommendations provided with risk-based prioritization

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
